Frequently Asked Questions
Are the calculators and converters really free?
Yes. Every calculator and converter on CalculatorEver is free to use. You do not need an account or a sign-up.
Are the numbers I type saved or sent anywhere?
No. The sums are worked out in your browser and the numbers are not sent to our servers. A few choices, such as your calculation history, your Favorites and your currency symbol, are saved on your own device only. The Privacy Policy explains this in full.
How accurate are the results?
Each page shows the formula it uses, and we test our answers against independent calculations. Results are still estimates for general information and not financial, medical, tax or legal advice, so please check important decisions with a qualified professional.
